As with previous “recipe” posts, this one is for me to remember in the future how to convert all FLAC files in a directory to OGG-Vorbis easily. The main motivation between this is making some lighter files to drop them in a Nokia N900 (at last, I have a device that can play them!) and save some disk space.

The recipe uses GStreamer’s gst-launch command:

for i in *.flac ; do
  gst-launch-0.10 filesrc location="${i}" 
    ! flacdec ! audioconvert ! vorbisenc quality=0.5 
    ! oggmux ! filesink location="${i%.flac}.ogg"
done

So, just copy-and-paste the recipe above as needed :-D
